Yeah, 4/5 images/second as compared to 6 images/second. Huge, huge difference ...

It is, but more importantly, the buffer on the D800locks up completely when it's full, so your camera is out of action for quite a while while it empties.

After 17 lossless compressed, 14-bit images the buffer is full. Is it really a big deal? I mean, if yes then sure, the D800 is poor performer, but how deep is the 5D3 buffer? with 6fps it fills faster, so it must be much deeper.

Isn't that 17 lossless compressed 14 bit frames on a 1000x Lexar CF card?

No, it's with 8 GB Toshiba R95 W80MB/s UHS-I SDHC card, but...

...the type of card and buffer size are not related. The buffer size is fixed. Card type matters only for how fast the buffer is transferred to the card, not changing the actual buffer size.

The point of course is not that there's anything wrong with the buffer, rather that the files are lossless compressed 14 bit  are big and there are no options for shooting at lower resolution. It's amazing that the D800 can even manage that throughput.

So what is it with lossless compression? It is called lossless because not a single bit of information is lost. Anyway, the buffer size is 16 raw for uncompressed images if you absolutely must shoot uncompressed, but that is pointless in my opinion because it adds nothing else than increased file size.

It's not that the 5D3 buffer is better, it's that the 5D3 files are smaller and that the buffer can cope more easily.  Add to that the Sraw option on the 5D3, and it simply offers more options.

In which way Canon raw "offers more options" than Nikon NEF? Of course the 5D3 files are smaller. Less MP = smaller files. How easily the camera can cope with the file size depends on much more than the file size, processor, transfer speed, memory speed and so on are all related to that, not just the file size.
